Soft Sensor for Online Cement Fineness Predicting in Ball

fineness are available on the market, they are expensive and, due to their exposition to fine particles from the ball mill, they require constant cleaning and maintenance [6]. In recent years, some studies have been conducted to develop models capable of estimating the cement particle size for the ball and vertical mills [7]–[9].

Soft Sensor for Online Cement Fineness Predicting in Ball

This paper describes the design and implementation of a soft sensor based on a backpropagation neural network model to predict the cement fineness online in a ball mill. The input variables of these models were selected by studying the cement grinding process, applying Spearman’s rank correlation, and the mutual information (MI) algorithm.

Ball Mills Ball Mill-Cylindrical Manufacturer from Meerut

The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then are being separated, and the coarse part being returned to the mill inlet.

Cement mill Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs

Vertical Roller Mills for Finish Grinding Industrial

Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator as opposed to the use of VRMs as pre-grinding to ball mills is regarded as a breakthrough.

Effect of ball and feed particle size distribution on the

This analysis technique showed that the required product fineness is a function of grinding media and feed material size distributions. It was also observed from the experimental results that in order to increase the milling efficiency of a ball mill, towards optimum production of material in the desired size class, there is a need to correlate
